Choose this one if you like:
1. Prime location. Within 5-min walking distance, there are BTS, MRT, bars, restaurants, shops etc, you don't want to walk in Bangkok under the sun for more than 10mins, trust me.
2. Easy check-in, the instruction was clear and all self-service.
3. Nice building, modern décor and friendly staff, spacious (at least for me) for single traveller or maybe a couple, however, 8-night stay came with only two tiny rolls of tissues, host advised no re-fill, and to buy some from 7-11 if I'd like.
4. The beddings were worst than $10/night hostel which is the most disappointing thing. I thought it was only the sheets, when I contacted Berry, she/he advised there was no replacement and to wash them myself. When I took off the sheets and pillow cover, I noticed the pillow was covered with stains and the quit smelled terrible. It is such a pity, hopefully this will be improved.
